10K white gold cross pendant Kessler’s

This was a gift from my ex but I need to sell it to pay for tuition! This 10K white gold cross pendant features 16 full cut round diamonds weighing 1/3ct. t.w. Just got it this Christmas and worn a handful of times so it’s in like new condition. Feel free to make offers but I don’t want to go down on the price too much :) thank you
